Astronomers are hustling to use interplanetary spacecraft to study the interstellar comet dubbed 3I/ATLAS while the sun is hiding it from Earth

Astronomer Avi Loeb outlines nine "anomalies" that he says support his hypothesis that interstellar object 3I/ATLAS is an alien artefact.

The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas surrounding it.

New images of the 33-million ton interstellar object confirmed it is releasing a nickel alloy commonly used in the aerospace industry, Harvard astrophysicist Dr. Avi Loeb revealed.

Lancaster lecturer Dr Norris said it is clear Oumuamu was not a spaceship, and he has not seen any proof so far that 31/ATLAS is behaving abnormally either. In a blog post earlier this month, Dr Loeb said he put the chance of the comet not being ‘fully natural’ at 30 to 40%.

As comet 3I/ATLAS nears its 29 October perihelion, scientists test whether its acceleration hints at alien propulsion—a bold 'mothership' theory led by Avi Loeb.

Space watchers are questioning if NASA’s Juno spacecraft could have observed 3I/Atlas, but the agency’s silence leaves the mystery unsolved.
